I want to simulate random access process of NB-IoT by Markov chain. When packets arriving at idle UE and this will lead to the UE from idle state to active state. Besides, packets arriving follow Poisson process. Then my question is in this condition how to determine the time duration of Poisson process?

Thank u.

In LTE random access procedure, if multiple UEs select the same preamble and send it to BS, there may have two conditions:
First, if these UEs have enough SNR, BS can detect a collision happen, then BS do not send RAR.
Otherwise, second, these UEs have a collision and BS can not detect all of them and send RAR, and all of these collision UEs can receive the same RAR.
My question is about the second one, there are multiple UEs use the same preamble, why BS do not know the collision ? why BS still send RAR to UEs ? why BS can still detect this preamble?

I read END sends PSS in entire one RB for sync, is it common for all the UE to get sync in case of NB_IOT UE?
